Much bigger targets - The most noticeable change is that the targets are far bigger, making it easy to see them even in bright sunlight (like this beach scene in my image here). I've really loved using this and it makes the capture process faster and more fun. Please try it this weekend, share your photo spheres on Google+ and Views (g.co/views), and let me know what you think!

Performance improvements - We also significantly reduced the memory consumption used during stitching. This, combined with some other fixes, will prevent some of the crash reports you've told us about. Note that all these changes also apply to the Pano, Wide Angle, and Fisheye modes, which are based on the Photo Sphere codebase.

The update has slowly trickled out, so most folks should have it downloaded by nor at at the very least having it showing as available for download. Have you grabbed it? If so, have you checked out the Photo Sphere updates? Let us know how they're working out for you in the comments if you have.
